Description
Technical field
The present invention relates to a kind of slow-release fertilizer, be specifically related to one and grow cotton Special slow release fertilizer and preparation method thereof, belong to agricultural fertilizer technical field.
Background technology
The global Important Economic crop of cotton is the main raw material of textile industry.China is that the world produces cotton and uses cotton big country, cotton national economy and and social development in occupy very important status, improve constantly the vital task that output of cotton and quality are agriculture productions.
The rational application of fertilizer is the important measures realizing cotton yield high-quality.But in the last few years, along with the increase of Cotton fertilization amount, output of cotton, cotton quality but do not significantly improve, and trace it to its cause, one is apply fertilizer not satisfy the need, and mostly payes attention to nitrogenous fertilizer, ignores phosphorus potash fertilizer; Two is pay attention to quick-acting fertilizer, ignores fertilizer and Controlled Release Fertilizer; Three is unreasonable owing to applying fertilizer, and cotton field soil fertility declines, and nutrient supply is unbalanced.Utilization rate of fertilizer is low, and loss is large, and environmental pollution is serious.In addition, adopt quick-acting chemical fertilizer, need repeatedly to apply fertilizer, time and effort consuming, not only increases production cost, also easily causes fertilizer damage.Therefore, development cotton Special slow release fertilizer, improves utilization rate of fertilizer, to realizing cotton yield high-quality and environment protection is very important.
Summary of the invention
For prior art Problems existing, the invention provides one to grow cotton Special slow release fertilizer, this slow-release fertilizer is for Developmental of Cotton feature and nutritional needs, discharge slowly lasting for desired nutritional element, only apply fertilizer once, both saved a large amount of manpower and materials, also improve utilization rate of fertilizer, environmental friendliness, improves edatope, improves output of cotton and fibrous quality.
Present invention also offers a preparation method growing cotton Special slow release fertilizer, the method can improve the utilization ratio of each nutritive element, meets the nutritional needs of cotton different times.
The technical scheme that the present invention is adopted to achieve these goals is:
The invention provides one to grow cotton Special slow release fertilizer, comprise following raw material to be prepared from: glucose lactones 82-98 part, soya-bean cake 40-50 part, urea 210-230 part, monoammonium phosphate 110-120 part, Repone K 60-80 part, Rhizoma amorphophalli powder 25-30 part, hexa metaphosphoric acid potassium 20-25 part, clover 60-80 part, rhizoma cyperi 50-70 part, guayule 80-90 part, chicken manure 40-50 part.
Further, above-mentioned cotton Special slow release fertilizer adopts following methods to be prepared from:
(1) half Rhizoma amorphophalli powder is added saturated sodium bicarbonate aqueous solution and regulate PH to 9, add hexa metaphosphoric acid potassium and stir, obtain mixed solution for subsequent use;
(2) clover, rhizoma cyperi, guayule are ground to 60-70 order powder, add urea and water, leave standstill 20min, then 15min is stirred with the rotating speed of 300r/min, add chicken manure, after stirring, at 38-40 DEG C of condition lower seal 3d, then add above-mentioned mixed solution, the granulated fertilizer obtaining 1-1.5mm after granulation, drying is for subsequent use;
(3) glucose lactones is added strong phosphoric acid, maleic anhydride, after stirring, at 60-80 DEG C of insulation reaction 100min, add the saturated potassium hydrogen carbonate aqueous solution and regulate pH value to neutral, obtain modified glucose lactones, then second half Rhizoma amorphophalli powder is added, soya-bean cake, monoammonium phosphate, Repone K, being sprayed at above-mentioned particle surface after stirring to particle diameter is 2.5-3.5mm, after oven dry.
Further, in step (2), the add-on of described water account for clover, rhizoma cyperi, 4 times of guayule three gross weight.
Further, the water content of chicken manure used in the present invention is 25-30%.
Further, described strong phosphoric acid is the phosphate aqueous solution containing 85% phosphoric acid.
Further, the mol ratio of described gluconolactone, strong phosphoric acid is 3:7.
Further, the add-on of described maleic anhydride accounts for 1.8% of gluconolactone.
Slow-release fertilizer provided by the invention, undertaken coated by the gluconolactone of modification, the thickness of coating layer plays an important role for release rate, by adjusting the thickness of coating layer, can conditioned fertilizer product release period, coordinate the supply of nutrient in each period, thus meet the nutritive element required for cotton different growing stages.The glucose lactones of modification can carry out a Shu Zuoyong to soil, increases the ventilation property of soil, control soil compaction.Containing abundant selenium element in clover, rhizoma cyperi, for raising cotton resistance and cotton fibre quality, there is vital role.
Advantage of the present invention is:
(1) slow-release fertilizer provided by the invention is according to the demand rule of cotton different times to nutritive element, rationally composite, fertilizer efficiency is long, can by nutritive element slow releasing, single-dose application can meet the nutritive ingredient required for cotton whole vegetative period, pollution-free, residual, can improve edatope, cheaper starting materials is easy to get;
(2) the present invention is simple in preparation method, and toxicity is low, does not develop immunity to drugs, and usage quantity is few, reduces production cost;
(3) output of cotton of planting is high, quality better.
